CPT® Code 64763

The procedure described by CPT® Code 64763 involves the transection or avulsion of the obturator nerve, which is located outside the pelvis (extrapelvic). The obturator nerve is a critical nerve that originates from the lumbar plexus, travels through the pelvis, and enters the thigh via the obturator canal. This nerve is responsible for innervating the adductor muscles of the thigh, which are essential for movements such as bringing the legs together. In this procedure, a surgical incision is made over the lateral aspect of the hip, allowing access to the underlying tissues. The surgeon dissects through the subcutaneous layers to expose the adductor tendon, which may be incised if necessary to facilitate access to the nerve. The anterior branch of the obturator nerve is then identified and either transected, meaning it is cut, or avulsed, which involves forcibly separating it from its connection to the main obturator nerve. This procedure may be indicated for various conditions affecting the obturator nerve or its function, and it is important to note that it is distinct from CPT® Code 64766, which pertains to an intrapelvic approach to the same nerve.
